DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character data conversion / transfer system, and more particularly to a different operating system (OS).
The present invention relates to a character data conversion and transfer method for converting and transferring character data between computers operating on a computer.

[0002]

2. Description of the Related Art As an example of this type of character data conversion transfer method, a shift JIS code, which is a Japanese character code, is transferred from a personal computer operating on MS-DOS developed by Microsoft, which is widely used as an OS for a personal computer. Is also transferred from a personal computer to a workstation operating on UNIX developed by ATT, which is an OS such as a higher-level computer. In this case, it is necessary to convert character data based on the shift JIS code into character data based on 8-bit JIS, which is one of UNIX Japanese character codes.

[0003] In the conventional character data conversion and transfer method, as shown in FIG.
The data is converted into character data by the character code of the OS of the transfer destination.

In FIG. 3, a conventional character data conversion and transfer method uses MS-DOS as an OS and shift JI to be transferred.
A personal computer 3 including a character data file 11 in S code and a transmission unit 12 for transferring the file 11
Receiving unit 2 that receives UNIX as an OS and receives transfer data
1, a file 22 for storing received character data, a character code conversion unit 23 for converting character data based on shift JIS code of received character data into character data based on 8-bit JIS, and a file 24 storing converted character data.
And a workstation 4 having the following.

Next, the operation of the conventional character data conversion transfer system will be described.

FIG. 4 is a flowchart showing the operation of the conventional character data conversion and transfer system shown in FIG.

In FIG. 4, first, in the transfer source personal computer 3, the file name of the character data file 11 storing the character data to be transferred and the OS (UNIX) name of the transfer destination are read (step P1). ).

Next, the contents of the file 11 are transferred to the workstation 4 via the transmission section 11 (step P).
2).

The work station 4 stores the character data transferred via the receiving section 21 in the file 22 (step P3).

Next, the shift J stored in the file 22
The character data based on the IS code is read out, converted into 8-bit JIS character data by the character code converter 23, and stored in the file 24 (step P4).

[0011]

In the conventional character data conversion and transfer method described above, the character data of the transfer source OS is transferred as it is, and the transfer destination character data is converted to the character data of the transfer destination OS character code. If the character code of the source OS is processed at the transfer destination due to forgetting to convert the character data due to an erroneous operation, etc., the character code is incompatible with the OS. There is a disadvantage that a problem occurs. In addition, since the system is individually constructed each time transfer between specific OSes is necessary, there is a drawback that there is no versatility.

[0012]

According to the character data conversion / transfer method of the present invention, first character data encoded by a first character code in a first operating system operates in a second operating system. In a character data conversion / transfer method for converting and transferring to second character data coded by a second character code in the second operating system of the processing device, the first and second operating systems may include: An operating system use character code list in which a name and a comparison between the first and second character codes respectively corresponding to the first and second operating systems are described, and the first character A character code comparison table in which the second character code corresponding to the code is described, It is constituted by a character code conversion unit that converts the character code to the second character codes by the character code correspondence table.

[0013]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the character data conversion / transfer system of the present invention.

In this embodiment, as in the above-mentioned conventional example, MS
An example will be described in which character data based on shift JIS code is converted into character data based on 8-bit JIS from a personal computer operating on DOS and transferred to a workstation operating on UNIX (4.3 BSD).

As shown in FIG. 1, the character data conversion and transfer system of this embodiment includes a personal computer 1 as a transfer source and a workstation 2 as a transfer destination.

The personal computer 1 is an MS-DO
S is an OS, and a character data file 11 based on shift JIS code to be transferred, and names of all the OSs targeted by the system and O character, which is a list describing a comparison between the character data used and the names of the OS. Code list 13
And a character code comparison table 1 for comparing the character codes described in the OS use character code list 13 including the description of the 8-bit JIS code corresponding to the shift JIS code.
4, a character code conversion unit 15 for converting a character code according to a character code comparison table 14, a file 16 for storing the converted character code, here, character data based on an 8-bit JIS code, and a file 16 which is sequentially read and transferred. And a transmission unit 12 that performs the transmission.

An example of the OS use character code list 13 is shown in Table 1.

[0019]

The workstation 2 has a UNIX (4.
3BSD) as an OS and a receiving unit 21 for receiving transfer data
And a file 24 for storing received character data.

Next, the operation of this embodiment will be described.

FIG. 2 is a flowchart for explaining the operation of the embodiment shown in FIG.

First, a file 11 in which character data input by the user and which is to be converted and transferred is stored.
File name and the OS (machine) name of the transfer destination are read.
Here, the file name is MS-DOS. JXW and the OS name of the transfer destination are set to 4.3 BSD which is one of the versions of UNIX (step S1).

Next, the used character code of the transfer destination OS read with reference to the used character code list 13 is represented by 8 bits J.
It recognizes that it is an IS code (step S2).

Next, a check is made as to whether the character data of the file 11 is the end (step S3). If no, go to step S4 to shift J of file 11.
Reads one unit of IS code character data.

Next, with reference to the character code comparison table 14, the character data of the 8-bit JIS code corresponding to the character data of the shift JIS code read in step S4 is read (step S5).

Next, the read character data of the 8-bit JIS code is temporarily stored in the file 16 (step S).
6).

The processing of steps S3 to S6 is continued until the end of the character data of the file 11.

Next, if YES in step S3, that is, if the character data of the file 11 is ended, the flow branches to a data transfer process, and mutual O is performed according to the system information input in advance.
The connection form between S is recognized (step S7).

Finally, the data temporarily stored in the file 16 is transferred to the transfer destination workstation 2 via the transmission unit 12.
And the process ends (step S8).

[0031]

As described above, the character data conversion and transfer method of the present invention uses an operating system in which the names of all operating systems targeted by the system and the corresponding character codes are described. By providing a character code list, a character code comparison table for comparing between character codes, and a character code conversion unit for converting character codes based on the character code comparison table, it is possible to avoid forgetting to convert character data due to an erroneous operation. Transfer source O
The character code of S is not processed as it is at the transfer destination, and it is possible to prevent the occurrence of troubles such as display disorder of the character display device due to incompatibility of the OS of the character code. In addition, there is an effect that the system has versatility that can support transfer between all OSs targeted by the system.
